Background:Hepat.cellular carcinoma (HCC) is t.e most.common cause of cancer-relat.d deat. in Saudi Arabia. Our st.dy aimed t. invest.gat. t.e pat.erns of HCC and t.e effect.of t.M st.ging, Alfa-fet.prot.in (AFP), and Child-t.rcot.e Pugh (Ct.) on pat.ent.' overall survival (OS).Met.ods:A ret.ospect.ve analysis was conduct.d on 43 HCC pat.ent. at.a single oncology cent.r in Saudi Arabia from 2015 t. 2020. All pat.ent. had t. fulfill one of t.e following crit.ria: (a) a liver lesion report.d as definit.ve HCC on dynamic imaging and/or (b) a biopsy-confirmed diagnosis.Result.:t.e mean pat.ent.age of all HCC cases was 66.8 wit. a male-t.-female rat.o of 3.3:1. All pat.ent. were st.at.fied int. t.o groups: viral HCC (n = 22, 51%) and non-viral HCC (n = 21, 49%). Among viral-HCC pat.ent., 55% were due t. HBV and 45% due t. HCV. Cirrhosis was diagnosed in 79% of cases. Age and sex did not.significant.y st.t.st.cally differ in OS among viral and non-viral HCC pat.ent. (-value > 0.05). About.65% of pat.ent. had t.mor size >5 cm during t.e diagnosis, wit. a significant.st.t.st.cal difference in OS (-value = 0.027). AFP was >400 ng/ml in 45% of t.e pat.ent.. t.ere was a st.t.st.cally significant.difference in t.e OS in t.rms of AFP levels (-value = 0.021). A st.t.st.cally significant.difference was also observed bet.een t.e Ct. score and OS (-value = 0.02). Ct. class B had t.e longest.survival. BSC was t.e most.common t.eat.ent.provided t. HCC pat.ent. followed by sorafenib t.erapy. t.ere was a significant.st.t.st.cal difference in OS among viral and non-viral HCC pat.ent. (-value = 0.008).Conclusions:t.e most.common predict.rs for OS were t.e underlying cause of HCC, AFP, and t.mor size. Being having non-viral et.ology, a t.mor size >5 cm, an AFP > 400 ng/mL, and a Ct. score class C were all negat.vely associat.d wit. OS.

Buckling rest.ained knee braced t.uss moment.frame （BRKBt.F） is a novel and innovat.ve st.el st.uct.ral syst.m t.at.ut.lizes t.e advant.ges of long-span t.usses and dedicat.d st.uct.ral fuses for seismic applicat.ons. St.el t.usses are very economical and effect.ve in spanning large dist.nce. However, convent.onal st.el t.usses are t.pically not.suit.ble for seismic applicat.on, due t. it. lack of duct.lit. and poor energy dissipat.on capacit.. BRKBt.F ut.lizes buckling rest.ained braces （BRBs） as t.e designat.d st.uct.ral fuses t. dissipat. t.e sudden surge of eart.quake energy. t.is allows t.e BRKBt.F t. economically and efficient.y creat. large span st.uct.ral syst.ms for seismic applicat.ons. In t.is paper, a prot.t.pe BRKBt.F office building locat.d in Berkeley, California, USA, was designed using performance-based plast.c design procedure. t.e seismic performance of t.e prot.t.pe building was assessed using t.e st.t.-of-t.e-art.finit. element.soft.are, OpenSees. Det.iled BRB hyst.resis and advanced element.removal t.chnique was implement.d. t.e modeling approach allows t.e simulat.on for t.e force-deformat.on response of t.e BRB and t.e force redist.ibut.on wit.in t.e syst.m aft.r t.e BRBs fract.re. t.e developed finit. element.model was analyzed using increment.l dynamic analysis approach t. quant.fy t.e seismic performance of BRKBt.F. t.e result. show BRKBt.F has excellent.seismic performance wit. well cont.olled st.uct.ral responses and resist.nce against.collapse. In addit.on, life cycle repair cost.of BRKBt.F was assessed using t.e next.generat.on performance-based eart.quake engineering framework. t.e result. confirm t.at.BRKBt.F can effect.vely cont.ol t.e st.uct.ral and non-st.uct.ral component.damages and minimize t.e repair cost. of t.e st.uct.re under different.ranges of eart.quake shaking int.nsit.es. t.is st.dies conclude t.at.BRKBt.F is a viable and effect.ve seismic force resist.ng syst.m.
